将私钥导入干净安装后，gpg —list-keys命令输出uid [未知]

我干净安装了Arch Linux，然后导入了备份的gpg私钥。作为健全性检查，我跑了：

gpg —list-keys

一切正常显示，但uid现在显示为：

uid [ unknown ] User < user@useremail.com >

当我在全新安装之前首次创建此密钥时，它显示为：

uid [ ultimate ] User < user@useremail.com >

为什么会从改变[ ultimate ]到[ unknown ]其导入到一个干净的安装后？

提前致谢。

GNUPG的信任数据库存储在 ~/.gnupg/trustdb.gpg

您可以使用以下--export-ownertrust选项备份此信任数据库：

gpg --export-ownertrust > file.txt

如果导出了密钥，以后又将其导入到新环境中，则信任数据库将不再存在。

但是，这很容易解决：

gpg --edit-key user@useremail.com

gpg> trust

Please decide how far you trust this user to correctly verify other users' keys
(by looking at passports, checking fingerprints from different sources, etc.)

  1 = I don't know or won't say
  2 = I do NOT trust
  3 = I trust marginally
  4 = I trust fully
  5 = I trust ultimately
  m = back to the main menu

Your decision? 5

并且不要忘记保存更改：

gpg> save
